v To all 'whom t may concern.'

il is a plan view Be it known that l, CLAUDE Vieron FUL- frox. subject ot the King of Great Britain, residing at Ztl lsmond street, llyde Park, in the State oi South Australia., Commonwealth of Australia, electrical engineer, have invented certain new and useful improvements in Disiniecting and Deodorizing De vices for vSanitary Flush Apparatus, of which the following is a specification.

lily invention relates to an improved disiu'fecting and deodorizing device for sani tary iiush apparatus, and has for its object to provide means whereby the last portion olf the dash tor sanitary pans and the like may contain disintecting and deodoriaing material or chemicals, the application o'rf such appliance being entirely automatic.

lf'litherto it has been customary to use disintectants in connection with sanitary pans, but the greater part ci such disinfectants when contained in the Hush reservoir are carried away with the stream, and very little remains in the pan and Water seal after the flush has been completed. Now, my invention aims at providing a device which will leave the greater part of the disinfecting inatlrial in the pan after the bulk of flush water has been carried away.

For the purpose of achieving this object l provide an auxiliary receptacle of compara.- tively small size which is connected With the rain down pipe o'l" the flushing system, and is so arranged that disinfecting or deodorizing material contained in the auxiliary chamber is diluted by the first Hush Water under pressure, and by siphon action is discharged into the pan at the end of the this ing operation.

ln order that my invention may he the better understood l will now proceed. to describe the same by aid of the accompany ing illustrative drawings Whereinzf Figure l is a front elevational view, partly in section, of my improved device; Fig. 2 a vertical sectional view of means for attaching the same to a flush pipe; and Fig.

thereof, partly in section.

Referring to the drawing, o is the flush pipe leading from the cistern to the places to be flushed. Leading from this flush pipe l arrange a smaller pipe d, 1which may be termed the inlet pipe.l One end of this pipe may be either upturned or out away at e so as to catch a portion of the downwardly flowing flush Water, the quantity of which may be regulated by a stopcock such as f, such coclr if so desired being graduated so that it may easily be set to suit the capacity of the overhead cistern. The opposite end of the inlet pipe leads into an auxiliary receptacle in the form of a drum or reservoir g,'\vliich is preferably made of metal, and may be provided at itsloiver end with Aan internally arranged cup h.

Upon the upper portion of the drum or reservoir l place a storage vessel 7c which contains liquid disinfectant. This storage vessel is arranged upon what is known as the bird. fountain principle, and is preferably made of glass, and may vary in size and shape. For operation it may be convenient to supply a screw neck or stopper l, through which a` discharge pipe m for the disinfectant passes, and conveys the disinfectant from the storage vessel to the cup shaped portion of the drum or reservoir, the device being like an inverted bottle, as Will he 'well understood.

To more completely embody the bird fountain principle a small portion of the discharge pipe m, is cut away at fnJ so as to allow the disinfectant to discharge up to the level of the lout away portion, after which y it becomes automatically sealed by the quantity of disinfectant that has been allowedto tion' into the cup shapedportion up to such level.

ln Fig. l the cup h is shown as being" mounted inside of the auxiliary receptacle g, and has a sunkenportion which receives the end of the discharge pipe m and seals it when a very small quantity of disinfectant has passed from the. storage vessel into the cup. The inflow of flush Water passes into the auxiliary chamber through the pipe d. The dow enters through the bottom of the chamher g, spreads out under the inserted dup,

and up the sides until it4 flows into the cup, l`

the quantity being regulated by theta-p f.I When the inflow has reached a sufficient height it sets a` small siphon pipe o arranged in cup h in operation. and the diluted disinfectant passes back 'through the pipe d, and into the flush pipe This arrangement enables the said pipe a', to serve both for inflow .and outlet purposes.

Figs. 2 and 3 illustrate a method of mounting the device upon existing Hush pipes. By such arrangement a socket end is 'formed at g for attaehing the device to the flush pipe, and is held in position' by the clamp "ibo
